To all whomitmay concern} Be it known that I, HORACE G. STONE, a; citizenbf the United States, residing "inn Chicago, in the county of Cook and State of lllinois, have invented new and useful Improvements in Propelling-Wheels for Tractors and other Vehicles, of which the following is aspecification.

Vilhere the earth is soft or wet the propelling wheels of tractors and other vehicles slip more or less and mud sticks to the wheels and if chains or rigid lugs are placed on the tires of the wheelsthe spaces fill up with mud and the wheel slipsaround with little or no power of locomotion. Such wheels cannot be continuously scraped to remove the mud becauseof the chains or rigid lugs and in order to get sufiicient powerto pull loads or plows in such places the weight of the-machine is materially in creased causing large extra expense in building and operating which is very undesirable a The object of my invention is to overcome these obstacles and I do it with a propelling z'wheelwhich s cleaned from mud" at each revolution of the wheel and at the same time has projections from the rim of the wheel which are. also cleaned at eachrevolution of the wheel and which projections penetrate the" ground so .as to give force to the wheel. l a

When understood my invention is simple, not expensive to build or'operate and very eitective, Y

In my invention I use sliding bolts or vlugs about two inches in diameter a short out its entire outer circumference.

.lVhen each lug is'at or near the'top of the wheel it does not project from the outdistance apart sunk into :the wheel throughside circumference of the wheel; but as the wheel revolves the lug is gradually pushed out until it projects two inches when it reaches the ear'li and it stays outsaid two inches until it has passed through the earth below the wheel thus preventingthe wheel from slipping.

Then as the wheel revolves the lug-,rises at the rear ot'the wheel and the lug is withdrawn into tlie socket which cleans the lug from mud, &c. 3

Where the lugs are thus drawninto their respective sockets the outsidesurface-of the wheel is smooth and if any mud remains upon it a mud scraper removes it as the lugs Specification of Letter: Yaten't,

ets by a spring and by their own. weighta The lugs are pushed out twoinchcs at the preventing the scraper oc lugs and theweight of the of the heavy than the wheel and as the wheel revcives upward the mug rolls ofi' the ends of the];

lugs, springs pull the lugs hack into their sockets and so on continuously. The weight of the ring may be regulated to suit diiterent regions and conditions or. there may he two rings difi'ereut-in and weight so that one or the other may he used as desired. '1, ,7 1 i s,

However much 'mud thuercKmay he the wheel and the lugs are alwayscleanwhen they reach the groundand thelugs are pre pared to do as good work to. prevent stipping as they-did to begin with} andthere is no mud on the wheel to interferewith' its work or with the work of the lugs orto clog up-the spaces on the wheel between the It will be noted that when the ground is dry so that the use of the projections at the bottom of the wheel is unnecessary the ring may 'be removed from the! wheel; the lugs will theni -fall be drawn in hy the springs leaving the tire-ofzthe wheel smooth and suitable for a hard road.

Other advantages, 0b1edt5 and purposes of my invention will be apparent as it is better undcrstood from theffollowing d scription when considered in connection with the accompanying drawing illustrating a preferred embodiment ,thereoj,
